Assessment of MR blood-oxygen-level-dependent (BOLD) cerebrovascular reactivity under general anesthesia in children with moyamoya.

Background: Moyamoya is a progressive, non-atherosclerotic cerebral arteriopathy that may present in childhood and currently has no cure. Early diagnosis is critical to prevent a lifelong risk of neurological morbidity. Blood-oxygen-level-dependent (BOLD) MRI cerebrovascular reactivity (CVR) imaging provides a non-invasive, in vivo measure of autoregulatory capacity and cerebrovascular reserve.

To assess the workload involved in provider referral at a sexual health clinic, we studied the number of attempts required, the contact method used, the time taken and the success of provider referral for 230 contacts referred over a 3-year period. For 87% of these contacts, a mobile number was available; 78.
